The physical nature of an IOL depends mainly on the material it is made up of. Although surface changes on the lens capsule can manifest as capsular opacification, as often noted after cataract surgery, IOL surface changes are not common. Optic abrasions, pigment dispersion, discoloration and opacification are the possible surface changes that can happen in the optic. An optic of 3 mm to 4 mm covers the pupillary zone in a normal anatomical situation, and surface abnormalities in this zone risk disturbing the patient’s best corrected vision. Optic opacification (Read more...)

In patients with medically well-controlled chronic angle-closure glaucoma and cataracts, combined phacoemulsification and goniosynechialysis rather than phaco alone did not significantly affect the IOP-lowering effect, according to a study.“I tend to perform synechialysis along with cataract surgery empirically for patients with chronic angle-closure glaucoma (CACG),” co-investigator Chan Yun Kim, MD, PhD, who sought to determine if such a regimen had a substantial clinical impact on patient outcomes, said.

A 13-year-old girl was referred from an outside ophthalmologist with a complaint of a “gray line going straight through” the visual field in her left eye that began 2 days before presentation.

She denied any prior (Read more...)
